Smart Online University Party Building System Based on Association Rules Data Mining

The effort of data mining, especially in relation to association rules in real world business applications, is significantly important. Recently, association rules algorithms have been developed to cope with multidimensional data. In this paper we are concerned with mining association rules in data warehouses by focusing on its measurement of summarized data. We propose two algorithms: HAvg and VAvg, to provide the initialization data for mining association rules in data warehouses by concentrating on the measurement of aggregate data. These algorithms are capable of providing efficient initialized data extraction from data warehouses and are used for mining association rules in data warehouses.

Data mining of association rules provides the technology for discovering the interesting association or correlation from mass of data. Apriori algorithm can find all the frequent items from transactional databases, and eliminate non-frequent items. But, the Apriori algorithm for data mining of association rules always produces a large number of candidate items, and scans the database repeatedly. Z-Apriori algorithm, the improved Apriori algorithmfor data mining of association rules, is introduced. A numerical example about a supermarket is given to show that Z-Apriori algorithm can dig the weighted frequent items easily and quickly. The association rules and items which are more interested by customers and more profitable can be found by Z-Apriori algorithm, and they are also traditionally supported highly.

Many techniques for cleaning dirty data are based on enforcing some set of integrity constraints. Conditional functional dependencies (CFDs) are a combination of traditional Functional dependencies (FDs) and association rules, and are widely used as a constraint formalism for data cleaning. However, the discovery of such CFDs has received limited attention. In this paper, we regard CFDs as an extension of association rules, and present three general methodologies for (approximate) CFD discovery, each using a different way of combining pattern mining for discovering the conditions (the “C” in CFD) with FD discovery. We discuss how existing algorithms fit into these three methodologies, and introduce new techniques to improve the discovery process. We show that the right choice of methodology improves performance over the traditional CFD discovery method CTane.

Association rule mining is one of the fundamental research topics in data mining and knowledge discovery that identifies interesting relationships between itemsets in datasets and predicts the associative and correlative behaviors for new data. Rooted in market basket analysis, there are a great number of techniques developed for association rule mining. They include frequent pattern discovery, interestingness, complex associations, and multiple data source mining. This paper introduces the up‐to‐date prevailing association rule mining methods and advocates the mining of complete association rules, including both positive and negative association rules. © 2011 John Wiley & Sons, Inc.WIREs Data Mining Knowl Discov2011 1 97‐116 DOI: 10.1002/widm.10This article is categorized under:Algorithmic Development > Association Rules

The representation and the exchange of information originating from different data sources is an increasingly common need for companies and industries to integrate their operations and also to publish and trade information with government and other enterprises. For this purpose, there are many standards based on XML language that were created to allow effective data communication and exchange in a particular domain. In order to ensure data quality for XML data, this paper presents an approach based on conditional functional dependencies verification. Conditional dependencies are an extension of traditional database dependencies with the ability to enforce bindings of semantically related data values. The basis of our verification method is a generic grammarware for validating XML integrity constraints in one tree traversal. We use an attribute grammar to describe XML documents and constraints. Keywords: conditional functional dependencies, data quality, XML integrity constraints.

Product arrangement, known as product display, is the layout or way of structuring products, especially products companies apply to attract consumers. Although one of the scopes of sales in the market is the delivery of information through galleries, storefronts require specialization and the ability to arrange products or displays following the standards and specifications of the company and the product itself. The resulting output directly affects the level of sales and information to be achieved in a store, especially in modern retail stores with a self-service format (self-service) such as minimarkets. To implement a display system, Data Mining is applied as a determinant of the layout of the merchandise. According to (Kusrini & Lutfi 2009), data mining is used to extract knowledge from databases. One of the many methods in Data Mining is the Apriori Algorithm. The a priori algorithm is a type of association rule in data mining. Association rule or association rule mining is used to find associative rules between item combinations to be used as wisdom to make decisions and provide a stock of products that consumers prefer

The discovery of association rules in data mining is an important issue, the core of which is the frequent pattern mining, Apriori algorithm is classical for the association rule mining, but it should repeatedly scan the database and can produce plenty of candidates. By examples, it is proved that Boolean matrix association rules algorithm can improve the algorithmic efficiency by reducing the times of accessing database and without producing candidates.

Association rules in data mining are considered from a point of view of Chellas’s conditional logic. Thereby the association rules with full and no confidence can be naturally translated into conditionals. Further, an extension of conditional logic is introduced for dealing with association rules with intermediate values of confidence based on fuzzy-measure-based semantics.

A robust associative watermarking technique based on vector quantization

Data mining is the process of finding correlations or patterns among dozens of fields in large relational databases. In this paper we propose a novel association rules for data mining to improve the famous algorithm Apriori. The proposed approach uses the intersection operation to generate frequent item sets. It is different from the existing algorithm as it scans the database only one time and then uses the database to mine association rules. The proposed technique has been implemented in a teaching evaluation system, to enhance the foundation in performance evaluation for staff in teaching issues.

Study on the Method of Road Transport Management Information Data Mining based on Pruning Eclat Algorithm and MapReduce

The notion of rules is very popular and appears in different flavors, for example as association rules in data mining or as functional (or multivalued) dependencies in databases. Their syntax is the same but their semantics widely differs. In this article, we focus on semantics for which Armstrong’s axioms are sound and complete. In this setting, we propose a unifying framework in which any ”well-formed” semantics for rules may be integrated. We do not focus on the underlying data mining problems posed by the discovery of rules, rather we prefer to emphasize the expressiveness of our contribution in a particular domain of application: the understanding of gene regulatory networks from gene expression data. The key idea is that biologists have the opportunity to choose – among some predefined semantics – or to define the meaning of their rules which best fits into their requirements. Our proposition has been implemented and integrated into an existing open-source system named MeV of the TIGR environment devoted to microarray data interpretation.KeywordsGene Expression DataAssociation RuleFunctional DependencyGene Regulatory NetworkMicroarray Data AnalysisThese keywords were added by machine and not by the authors.

Mining association rules is one of the most important tasks for uncovering hidden patterns in datasets to aid organizations in making efficient decisions based on customer behavior and preference. This association rule identifies other possible connections that may exist beyond customer preference and behavior. Some of the most prominent algorithms used in this regard are Apriori algorithms and FP-Growth algorithms. They help to obtain sufficient information based on huge datasets. However, association rule mining using existing algorithms has encountered several problems. They consume a huge memory space for data processing. They need data searching for finding out the frequency of each item. They also establish rules with low efficiency. In overcoming such problems engendered by data mining association rules, a better efficient Fp-TDA algorithm using advanced FP-Growth algorithms has recently been developed. This algorithm uses Matrix Tree instead of a tree concept used in existing algorithms. This largely cuts down data processing time. This concept largely cuts down frequently generated data. This concept largely addresses precision. This largely enhances data processing. This concept largely addresses efficiency. This largely addresses data quality. This largely addresses data time. This concept largely addresses memory space. The Fp-TDA largely addresses problems in association rule mining. This concept largely addresses data processing.

Many issues about data quality have been studied in relational data, such as data consistency, data deduplication, data accuracy, data completeness and so on. In this paper, we focus on the discovery of abnormal data in RDF graphs. As the amount of RDF data is increasing, data quality is becoming an important issue for usability of these RDF repositories. Although association rules have been used to find abnormals in RDF graph, existing solutions ignore the latent semantics of connected structures in RDF graphs. In order to detect latent dependencies in RDF graph, firstly, we innovatively define Graph-based Conditional Functional Dependency(GCFD) that can represent the attribute value and semantic structure dependencies of RDF data in a uniform manner. Then, we propose an efficient framework and some novel pruning rules to discover GCFD in large RDF graphs. Extensive experiments on several real-life RDF repositories confirm the superiority of our solution.
